hello team

Suddenly my mini client doesn't start game. It was working fine till 4th July 2020 but now after loading 100% ,there is a black screen and nothing else.my server is S637 .

I tried loading from google chrome too but it also shows black screen.

I also tried things mentioned in post https://forum-narutoen.oasgames.com/page/show-post-39158-1.html but nothing works.here is screenshot of possible error but i don't know what to do.
